It is working now http://jsfiddle.net/sudiptabanerjee/m6x23/7/

Galleria.ready(function () {
Galleria.on('image', function (e) {
    if (this._active == this._data.length - 1) {
        $('.galleria-image-nav-right').hide();
    } else {
        $('.galleria-image-nav-right').show();
    }
    if (this._active == 0) {
        $('.galleria-image-nav-left').hide();
    } else {
        $('.galleria-image-nav-left').show();
    }
});

Galleria.on('lightbox_image', function (e) {
    if (this._lightbox.active == this._data.length - 1) {
        $('.galleria-lightbox-next').hide();
        $('.galleria-lightbox-nextholder').hide();
    } else {
        $('.galleria-lightbox-next').show();
        $('.galleria-lightbox-nextholder').show();
    }
    if (this._lightbox.active == 0) {
        $('.galleria-lightbox-prev').hide();
        $('.galleria-lightbox-prevholder').hide();
    } else {
        $('.galleria-lightbox-prev').show();
        $('.galleria-lightbox-prevholder').show();
    }
});

});
